Patent Images
1. A plasma addressed liquid crystal display comprising:
- first and second substrates filled with liquid crystal therebetween;
a plurality of striped data electrodes formed in parallel on an inner side of said first substrate;
a third substrate opposing an outer side of said second substrate;
a plurality of striped first electrodes placed on an inner side of said third substrate opposing said second substrate at right angles to said data electrodes;
a barrier of a predetermined height disposed between said first electrodes and parallel thereto; and
a second electrode stacked with each barrier, the flanks of said second electrode facing said first electrodes positioned adjacent to a corresponding barrier.

Abstract
A plasma addressed liquid crystal display and manufacturing method thereof is disclosed whose plasma addressing unit has a barrier of a predetermined height between a planar orientation layer and a rear substrate, a second electrode placed in the middle or on the top of the barrier, and a first electrode positioned between the barriers. The electrodes are made of metal paste which enables the use of a screen printing method, thereby facilitating manufacturing and allowing for a large screen display.

14. In a plasma addressed liquid crystal display including first and second substrates filled with liquid crystal therebetween, a plurality of striped data electrodes formed in parallel on the inner side of said first substrate, a third substrate opposing the outer side of said second substrate, a plurality of striped first electrodes placed in parallel on the inner side of said third substrate opposing said second substrate at right angles to said data electrodes, a plurality of barriers of a predetermined height, each barrier disposed between one of said first electrodes and parallel thereto, and a second electrode stacked with each barrier, the flanks of said second electrode facing said first electrodes positioned adjacent to a corresponding barrier, a method of manufacturing said plasma addressed liquid crystal display comprising the steps of:
-
forming first striped transparent electrodes in parallel on the third substrate; forming between said first electrodes an intermediate member of a predetermined height, each intermediate member including a barrier and a second electrode; adhering the second substrate of a predetermined thickness to the intermediate members with paste; aligning said second substrate with said first substrate so that said first and second substrates oppose each other and are spaced apart by a predetermined distance; and filling the space between said first and second substrates with liquid crystal. - View Dependent Claims (15, 16, 17, 18, 19, 20)
